To all whom it may concern Be it known that l, ALEXANDER Geckos S'FRA'THERN? o subject ofthc King oi? the United Kingdom of Great liritoiuend he land, :ind residing; at iloolibridge, l ienorkshire, Scotland, have invented a certain new and useful Improvement in Machinesior impressing Metal Bars by Rolling the Same, of which the following is a specification.

o This invention relates to mochines of the type having more than two rolls, soy four rolls, the outer tires, die rings or peripheries of which are of Wedge section and are [corresponding to the shape of chain links or other articles to be produced from in'etol bars of cruciform orother section.

The primary object of the invention is to provide on improved constructimi of mo- 3o chineoi this type wherein the rolls are adapted to be readily changed or replaced.

In the'occomponying drawing l igurcs l and 2 are elevations at right angles to each other o'T-o chitin-making machine cons 3ructed in accords-rice with the invention; 3 and 4t show a l-modification.

liihe'reference characters denote similar ports in the several figures of the drawing.

A eferring; to the drawing, the main frame to loft themochine is constructed with two pairs of recesses 2, or housings, arranged in lines intersecting one another at, right anglee, e. 9., "with two Vertical recesses end to o horizontal recesses leading from the center it of the frame.- "Within the recesses 2 are pivoted forked members includingtines or arms 4 the free ends of which. operating rolls 5 are carried in hearings Erich roll has bevel gear teeth 5 formed on the sides to thereof which, when the rolls are in open otive position, are designed to mesh with the teeth of their adjacent roll, that is to soy the rolls that are arranged ct right angles to each other. ldy this arrangement it Will be opporeut that all of the rolls will be oper ated simultaneously to thereby insure perfoot olinement of the impression surfaces thereof.

The tihes or each forked member may be to mode integral (see the horizontolly disposed members in Fig. 1) or fixedly connected, or each forked member may be divided, zrs indicetcd at 8, Figs. 1 and 3, into two elements secured on e common pivot disposed at the bottom of the recess transversely thereof.

2. A machine for impressing metal bars by rolling the same, comprising, in combination, a recessed frame, a plurality of cruciformly disposed fork-like members each member'being pivoted to said frame at one end and adapted to be oscillated out of the plane of said frame, bearing members carried by said members remote from the pivoted ends thereof, and rolls rotatably mounted in said bearing members.

3. A machine for impressing metal bars by rolling the same, comprising, in combination, a frame formed with recesses, divided forked members, and rolls carried by said forked members, said forked members and rolls being housed in said recesses when in operative position and adapted to be oscil l ated out of said recesses to shift said rolls into inoperative position. i 4. A machine for impressing-metal bars by rolling the same, comprising, in combination, a frame formed with recesses, forked members, and rolls carried by said'forked members, said members and rolls housed in said recesses when in operative position and adapted to be oscillated simultaneously out of said recesses to bring said rolls into inoperative position. i V

A machine for impressing metal bars by rolling the same, comprising, in combination, a frame, a plurality of rotatable rolls, crucifor'mly disposed forked members supporting'said rolls, each forked member pivoted tosaidfram e on an axis parallel with the axis of rotation of the roll carried thereby and adapted to be swung outwardly on members, said forked members and rolls being housedin said recesses when in operative position and adapted to be oscillated out ofsaid recesses to shift said rolls into inoperative position.

7. A machine for impressing metal bars by rolling the same, comprising, in combination with a frame, cruciformly disposed forked members pivotally mounted in said frame, a rotatable impressing roll carried at the outer end of each forked member, said forked members being pivoted on axes parallel with the axis of rotation of the said rolls, means for simultaneously swinging said forked members outwardly on their pivots. i
